A genetic vindication of a folk theory of race would find those common causes.

True, such vindication is not there.

But it is true that West Africans dominate the 100 meter, and East Africans the long distances. To quote from the link below:

No white sprinter can be found on the list of 100-meter sprinters; the best time by a white, 10 seconds, ranks more than 200th on the all-time list. Dozens of blacks, every one with a West African ancestry, have cracked the 10-second barrier, but no sprinter of any other race.

For a much more careful and detailed explanation of this, see TABOO: Why Black Athletes Dominate Sports And Why We're Afraid to Talk About It .

You are misconstruing what I'm saying, turning it into a paper tiger, and then demolishing it.

Do Races Differ in Athletic Ability?

Do races differ in athletic ability? Do Blacks really dominate sports? The answer to these questions is no. Unfortunately, this response flies in the face of commonly accepted logic. Most Americans believe that races are real and correspond to their common sense observations.

"it is true that West Africans dominate the 100 meter" Yes. And many people are tempted to make the inviting inference, and say "they dominate because they are black". That's an explanation which appeals to race. If it were true, it would be a vindication of a folk theory of race, ie the view that race plays an explanatory/causal role. What the article argues is that the folk theory of race is mistaken. I'll let you say whether you agree or disagree with that claim so as to avoid misatributing a view to you.
